Hot 97's annual Summer Jam lineup just got a little shadier: On Thursday morning (May 24), Eminem phoned into the New York hip-hop radio station to announce that his group Slaughterhouse will join Nicki Minaj, Rick Ross and 2 Chainz at New Jersey's MetLife Stadium on June 3.

This will be the first time Slaughterhouse will perform at the all-star hip-hop throwdown, so what advice does Marshall have for Joe Budden, Joell Ortiz, Crooked I and Royce da 5'9"? "Just be themselves," Eminem told Hot 97 and "Hip Hop Squares" host Peter Rosenberg. "I really feel like this group — hip-hop needs this, man, and I think people will see when this album comes out too."

King Mathers didn't hint at any surprise appearances. He is currently in the studio. "Right now, I'm finishing up everything on the Slaughterhouse album and kinda getting into my next record a little bit," he shared.

Em wouldn't dish any further on his upcoming seventh studio album, only saying that he is just "starting to toy" with the LP. Before that, SH will be dropping their Shady Records debut, Welcome to: Our House, in June.

"The album is done," Royce da 5'9" told MTV News on May 9 from the set of their "My Life" video. "In terms of vocal recording, we're done. Marshall is still in the process of mixing; we still got a couple of records that we're missing. We're on pace for June. Worst-case scenario, we're looking at July, but it's definitely coming — 100 percent."
